Description
Tianhua Jiang and nine colleagues identify in 2026 a gene switch that keeps chrysanthemums in their squat winter rosette form during long cold spells. Perennials survive winter by halting stem growth and flowering, yet the coordinator of both pauses was unknown. Prolonged chilling acted mainly at the shoot tip in their experiments.
Cold switched on a gene called CmDREBa in the apex rib zone. The gene's protein turned on MAF genes, known flowering brakes, which together enforced the rosette habit and blocked blooming. When warmth returned, CmDREBa levels fell and growth resumed. Jiang and co-authors present the gene as a key seasonal regulator that breeders might tune for climate resilience.
